NORRISTOWN, Pa. (AP) — Bill Cosby's chief accuser sent jurors into the weekend with a stark portrait of the night she says the man she viewed as a friend and mentor tricked her into taking a powerful drug and then humiliated her for his own sexual gratification. Andrea Constand testified Friday that she was visiting the "Cosby Show" star at his suburban Philadelphia mansion in January 2004 when he slipped her three blue pills he called "your friends." She thought they were herbal supplements that Cosby said would relieve her stress, but they knocked her out.
